I recently noticed Lady, one of my female budgies, spending time on the floor of the cage. The feathers on her back between her flight feathers were ruffled but she could still fly. I suspected a fight between Lady who is No2 and Jolie who is very much No1. She is eating and does not seem distressed except for her obvious fall from grace. It is autumn here, moulting has finished and the girls appear to be coming into season. Could this be the cause of this apparently aggressive behaviour? I was wondering whether I should separate Lady and check her over. (The vet has taught me how because I am a doctor.)
